Paul is a beast too- attended his first seminar (with Sarah, and Shane Church- 960lbs squatter @ 242). If you get a chance to learn from the Vallaincourts, please do. They were also selected by Defranco as part of his initial mentorship program.
Marshall's seems to allow chalk as long as you're respectful about it's use. I've had a couple DL sessions there and no one has said boo.
The website does lie a bit- no 125lbs dumbbells in sight. The trap bar is also a fuckin beast- York model weighing 80lbs. I've used a different model and found the York to be subpar, but whatever. The gym is pretty minimal- some bumper plates, about 4x 100 lbs plates, and 2 squat racks. It's basic, kind of quiet, and not far from my place. If you need something fancy, probably not the place for you.
Either way, get the fuck out of Goodlife. New Body on St Laurent has 120lbs dumbbells, but is more of a bodybuilding gym. I was training there before switching to Marshalls and they never had an issue with chalk etc. Hell, in the intro/tour I was told i could drop weights.
Lemme know if you need anything else via pm.
